[Relative hydrophobicity and other properties of lectins in aqueous binary phase polymeric systems]
Abstract:
The relative hydrophobicity of ten purified lectins preparations (SBA, LCA, PNA, PSA, STA, WGA, Con A, PHA-P, RCA-I and HPA) was determined using the aqueous two-phase polymeric system Ficoll 400-dextran 70 (13.53% - 11.59%, w/w in H2O, respectively). The linear correlation was found between the relative hydrophobicity of the lectin preparations and their hemagglutinating activity towards native rabbit erythrocytes (r2 = 0.925). Con A specific carbohydrate ligands added to the system decreased the relative hydrophobicity of lectin. Using cross partition, isoelectric points for the lectins were determined.

Aqueous Solutions and Heats of Hydration
When ionic compounds dissolve in water, the ions in the solid separate and disperse uniformly throughout the solution because water molecules surround and solvate the ions, reducing the strong electrostatic forces between them. This process...
Ligand Binding Sites
Protein-ligand interactions are quite specific; even though numerous potential ligands surround a cellular protein at any given time, only a particular ligand can bind to that protein. Moreover, a ligand binds only to a dedicated area on the surface of the protein, known as the...
Solubility
A solution is a homogeneous mixture composed of a solvent, the major component, and a solute, the minor component. The physical state of a solution—solid, liquid, or gas—is typically the same as that of the solvent. Solute concentrations are often described with qualitative terms such as dilute (of relatively low concentration) and concentrated (of relatively high concentration).
In a solution, the solute particles (molecules, atoms, and/or ions)...
